Your current installation of Bugzilla stores passwords in plaintext
in the database and uses mysql's encrypt function instead of Perl's
crypt function to crypt passwords.  Passwords are now going to be
re-crypted with the Perl function, and plaintext passwords will be
deleted from the database.  This could take a while if your
installation has many users.
